A Binary Compound
A binary compound is formed from two
types of elements - their states of matter result in the following types of
+ Metal = Metallic Compound
+ Non-Metal = Ionic compound
Non-Metal + Non-Metal = Covalent compound
Compounds - Categories - Ionic, Molecular and Acids
Most types of compounds fall in to one of
three categories called ionic compounds, molecular compounds, or acids.
Compounds - Ionic, Cations, Anions
An Ion is an atom, or group of atoms,
that bears an electric charge. The types of compounds referred to 'Ionic
compounds' consist of combinations of positively charged ions called
CATIONS (which are usually metals - pronounce as 'cat-ion') and negatively charged ions called
ANIONS (which are usually non-metals - pronounce as 'an-eye-on'). In general, a compound will have no
Positively charged ions are called cations because they migrate towards
the cathode (negative pole) in solution - they tend to lose electrons
and form cations
Negatively charged ions are called anions because they migrate towards
the positive pole (anode) and are therefore known as anions - non-metals
tend to gain electrons and form anions
positive cations and the negative anions then attract each other to form
compounds conduct electricity when dissolved in water or when molten

Types of Compounds - What is the difference between a compound
and a molecule?
Molecular compound. What is the
difference between a compound and a molecule?
A molecule is formed when two or more atoms join together chemically
compound is a molecule that contains at least two different elements
compounds are molecules, but not all molecules are compounds
Compounds - Molecular Compound
Molecular compounds consist of combinations of
non-metals. A Binary molecular compound is composed
of only two elements.
Examples: H2O (water).
are easy to identify, as they consist merely of two non-metal elements
are non-conductors of electricity
